About the role

Responsibilities

  • Design and build end-to-end agentic systems for creative tasks.
  • Develop novel approaches for training and adapting the large language models that power these agents.
  • Design objectives, datasets, and fine-tuning strategies to improve agent behavior and reliability.
  • Explore multimodal reasoning and structured generation for creative control.
  • Run systematic experiments to evaluate and improve agent performance in real-world tasks.
  • Design evaluation frameworks for agentic workflows in video analysis and editing.
  • Analyze failure modes across the full agent loop—including planning, tool use, and execution—and iterate on improvements.

Requirements

  • BS, MS, or PhD in Computer Science, Machine Learning, or a related field.
  • Strong track record building production ML systems or agentic pipelines.
  • Deep understanding of transformers and modern LLM techniques.
  • Experience with fine-tuning, alignment, or post-training methods, especially for adapting models to generate structured outputs or drive tool use.
  • Comfort owning the full stack, from model-level experiments to deployed agent systems.
  • Strong experimental rigor and good judgment about what makes agents work effectively in practice.

Benefits

  • Comprehensive medical, dental, and vision plans.
  • 401(k) with employer match.
  • Commuter benefits.
  • Catered lunch multiple days per week.
  • Dinner stipend for late work.
  • Grubhub subscription.
  • Health and wellness perks.
  • Multiple team offsites and monthly team events.
  • Generous PTO policy.
